ravine wind; canyon wind; gorge wind
A wind that blows through a narrow valley or gorge, often used in meteorology or geography contexts.
Ravine winds can increase in speed due to the valley's topography.
In this area, a strong canyon wind blows in the evening.
Compound of 峡谷 (kyōkoku, 'gorge, canyon') and 風 (fū, 'wind'). The term is a straightforward technical compound.
